Humor in Heroes of Might and Magic V.

I had a rather unpleasant bug:(I'll warn you right away: I haven't played the fifth game in a long time, so I might not remember many names/terms.) In the third mission for the Necromancer, where you have to defile cities, I was in one city when I saw a hero approaching (I don't remember the name, but his specialization was Goblins). He had an awesome army (for me at the time) and attacked me. We had a fierce battle... I lost... and so on. This happened about 10 times. I thought, "Well, I'll give it one more try..." We had another bloody battle. I specifically positioned myself near corpses so he couldn't resurrect them... Only Goblins remained... They were killed... But what's this? THE BATTLE DOESN'T END!!! Everyone died (his army), the hero remained, and he kept shooting at me... I was furious back then... And before that, in those 10 battles, sometimes mines from my own castle would affect me. But you'd think all these were just glitches, but no... I couldn't pass through that portal, which requires 20 Dragon Eggs, even though I had 20, and then 200 Dragon Eggs, even the upgraded portal wouldn't accept them (later I found out that some people had the same bug, and you have to enter a code to win). P.S. I don't know if all Elementals (even the ones that aren't summoned) die like summoned units, but sometimes that bluish flash (with which they die) would turn reddish
